Why does the mobile phone sometimes vibrate when sending text messages?

Take Huawei p40 and EMUI 10 as examples:

1, it may be that the mobile phone system has started the "vibration" mode, and then the mobile phone will vibrate once it receives the information.

Solution: Turn on the phone settings, and then turn off the "vibration" mode.

2. In addition to the mobile phone system, it is also possible that some applications in the background of the mobile phone constantly receive information, causing vibration.

Solution: You can clean up the background applications or turn off the application reminder function of the mobile phone.

3. It may be that the mobile phone turns on the call vibration reminder, alarm clock vibration reminder, task vibration reminder, etc.

Solution: Try setting the phone to "silent" mode.

4. It may be that there is something wrong with the system of the mobile phone, which leads to the confusion of some functions of the mobile phone.

Solution: Update the mobile phone system as much as possible, or back up the data of the mobile phone to restore the factory settings of the mobile phone.

It may be that some hardware faults of the mobile phone have caused this situation.

Solution: contact the mobile phone after sale and find a professional to check and repair it.

This answer applies to most brands of smartphones such as Huawei and Apple.
